Someone I am close to is prescribed to ambien and takes it on a regular basis. He says for the little while he is awake on it before falling asleep it gives him drive and motivation to do productive things, or to create something new. To influence the world somehow. However, after waking back up in the morning all this ambition is completely gone. What in ambien can cause that type of side effect? Also, is it possible to take a drug that is meant for having this type of effect so he could feel like this during the day?
